Typically, discounted app promotions on Apple’s App Store are initiated by the app developer, not Apple, and that may be the case with Cut the Rope:Experiments.

So this may be a joint Apple Zepto Labs promotion, or Apple may simply be using Zepto Labs’ announcement to promote a great free app on the App Store.

Apple recently used its ongoing “App of the Week” feature to promote Cut the Rope: Experiments as a free download.

Cut the Rope: Experiments is priced at 99 cents on the Amazon Appstore and Google Play.

Facebook is getting into the game as well, announcing recently that it will open an App Center where users can be redirected moreeasily to mobile app downloads as well as apps in the Facebook ecosystem and other Web apps.

As noticed by The Verge, the Editors’ Choice terminology has also been picked up in the Mac App Store, with Cobook [Mac App Store] being the initial recipient of the designation.

Deus Ex: Human Revolution [Mac App Store] has also been made an Editors’ Choice pick, but there appears to be no Free App of the Week in the Mac App Store to correspond with the feature on the iOS side, although Cobook is a free app.
